A judge ruled Wednesday that an Indiana man accused of brutally killing his estranged girlfriend is not currently competent to stand trial.

One psychiatrist and two psychologists who evaluated 36-year-old Joseph Oberhansely opined in a Wednesday hearing that he is not fit for trial on charges of murder, burglary and rape in the September 2014 slaying of Tammy Jo Blanton.

The ruling by Clark County Circuit Court Judge Vicki Carmichael is the latest delay in the case, which had been set for a June trial.

"I had hoped that it would be tried before now," said Clark County Prosecuting Attorney Jeremy Mull. "But my main priority is getting a verdict that is going to stand, that is going to survive appeal..."

The court-appointed professionals evaluated Oberhansley's ability to understand court proceedings and participate in his own defense.

Defense attorneys Brent Westerfeld and Bart Betteau filed a motion asking for the evaluations in February saying there was a "complete breakdown" in communication between them and Oberhansley, who appeared "suspicious, paranoid, uncommunicative, and agitated" in their interactions.

Oberhansley will now undergo treatment via the Indiana Division of Mental Health and Addiction, which is meant to bring him to competency so he can be tried at a later date.

It's unclear if Oberhansley can be brought to a level deemed competent by the judge.

The three evaluators didn't opine on Oberhansley's ability to attain competency, Mull said.
